How planes and helicopters fly

 

The reaction to this is a force pushing the plate in the opposite direction, upward.
             Another way of explaining Newton's third law of motion can be in terms of a helicopter. If the rotors are spinning at full speed, but the pilot positions their pitch so that the blades are perfectly horizontal, no lift will be created. Pitch is defined as the degree of inclination or slope. Now, the pilot increases their pitch by a few degrees. The spinning rotors will deflect the air downward. The reaction to this is that the rotors will be pushed upward. .
             There are four forces that act on planes and helicopters during flight. They are lift, weight, thrust, and drag. In summary, when an object is flying straight and level, lift works upward and is opposed by weight, which pulls the object toward the ground. Thrust is the propelling force that gives that gives the object speed. This keeps the aircraft a loft, and it is opposed by drag. Drag slows down the aircraft.
             There are three things that effect how much lift is created. They are speed, air density, and the shape of the propeller. If you increase the speed of an airplane, more air will be forced under the wing. Therefore, more lift will be created. If you increase the speed at which helicopters rotors are turning, more lift will be created. Another thing that affects the amount of lift created is the density of the air. The colder the air, the denser it is. Also, as the aircraft's altitude increases, the air becomes less dense. More lift is produced in denser air. The final thing that you can do to increase the amount of lift produced is to alter the propeller's shape. There are two ways in which you can do this. You can increase the pitch, and you can increase their length. Doing either of these will also increase the amount of lift produced.
             To fully understand the principles of flight, however, one needs to become familiar with a few more technical terms.
